Details of Public Consultations EXECUTIVE SUMMARY The Tamil Nadu Urban Flagship Investment Program (TNUFIP) will advance India’s national urban flagship programs to develop priority urban and environmental infrastructure in ten cities located within strategic industrial corridors of Tamil Nadu (the State), including those within the East Coast Economic Corridor (ECEC), to enhance environmental sustainability, climate resilience, and livability. It will also strengthen the capacity of state and local institutions and improve urban governance. TNUFIP is aligned with the following impacts: (i) universal access to basic water and sanitation services achieved; (ii) “world-class” cities and industrial corridors across the state developed; and (iii) water security, reduced vulnerability to climate change in urban areas, and enhanced share of renewable energy achieved. TNUFIP will have the following outcome: livability and climate resilience in at least 10 cities in priority industrial corridors enhanced. The TNUFIP is structured under three outputs: (i) climate-resilient sewage collection and treatment, and drainage systems developed in at least eight cities; (ii) water supply systems in at least five cities improved with smart features; and (iii) institutional capacity, public awareness, and urban governance strengthened. TNUFIP will be implemented over an 8-year period beginning in 2018, and will be funded by Asian Development Bank (ADB) via its multitranche financing facility (MFF). The Subproject. Coimbatore, located in the central western part of Tamil Nadu, is second largest city in the state after capital Chennai. In this subproject to be implemented under the ADB funded TNUFIP, it is proposed to provide underground sewerage system in added areas (Kuruchi and Kuniamuthur) of Coimbatore City Municipal Corporation (CCMC). These areas are located in the southern outskirts of the city. Subproject includes the following civil works components: (i) sewer network (434.52 kilometers [km] length of sewers and 17,748 manholes); (ii) 19 lift stations; (iii) 5 lift manholes; (iv) 11 pump stations (including 4 main pumping stations); (v) pumping mains (42.985 km); (vi) sewage treatment plant (STP) of 30 million litres per day (MLD) capacity; (vii) 2 megawatt (MW) photo voltaic solar power plant at STP site; and (viii) 69,668 house service connections. Project Implementation Arrangements. The Municipal Administration and Water Supply Department (MAWS) of GOTN acting through the Tamil Nadu Urban Infrastructure Financial Services Limited (TNUIFSL) is the state-level executing agency. A program management unit (PMU) will be established in TNUIFSL headed by a Project Director and Deputy Project Director (senior official from Commissionerate of Municipal Administration, CMA), and comprising dedicated full-time staff from TNUIFSL for overall project and financial management. The implementing agencies are project urban local bodies (ULBs). CCMC is the implementing agency for this subproject. A program implementation unit (PIU) will be established in CCMC headed by a full-time Project Manager (Executive Engineer or above) and comprising dedicated full-time staff of the CCMC for day-to-day implementation of the subproject. PIU is assisted by construction management and supervision consultant (CMSC) in implementation. Environmental and social safeguards (ESS) Managers in PMU/TNUIFSL will coordinate all the safeguard related activities of the subproject and will ensure the compliance with environmental management plan (EMP) and environmental assessment and review framework (EARF). Environmental Specialist of the CMSC will assist PIU in implantation of subproject in compliance with EMP and EARF, and will carry out all necessary tasks. Screening and Assessment of Potential Impacts. ADB requires the consideration of environmental issues in all aspects of the Bank’s operations, and the requirements for ii environmental assessment are described in ADB’s Safeguard Policy Statement (SPS), 2009. As per the Government of India Environmental Impact Assessment (EIA) Notification, 2006, this subproject do not require EIA study or environmental clearance. The potential environmental impacts of the subproject have been assessed using ADB Rapid Environmental Assessment Checklist for Sewerage. The potential negative impacts were identified in relation to pre- construction, construction and operation. Categorization. Based on results of the assessment and ADB SPS 2009, the subproject is classified as environmental Category B, i.e., subproject potential adverse environmental impacts are less adverse than those of category A, and are site-specific, and in most cases mitigation measures can be designed more readily than for category A projects. An initial environmental examination (IEE) is required. Description of the Environment. The subproject components are located in Kuniamuthur (87- 93 wards) and Kuruchi (93-100 wards) areas in the southern suburbs of Coimbatore City. Kuniamuthur and Kuruchi are erstwhile municipalities added to Coimbatore CityMunicipal Corporation in 2011. Located on Coimbatore – Palakkad Road, Kuniamuthur is one of busiest markets in the city. Kurichi is an industrial cluster, with two industrial estates. Coimbatore district forms part of upland plateau region of Tamil Nadu with many hill ranges, hillocks and undulating topography with a gentle slope towards east except for the hilly terrain in the west. Both Kurichi
